標題[問題] 莫名的undeclare scope
時間Wed Dec 2 22:33:58 2009
以下是我程式片段的bug：
../../include/dlist.h: In constructor 'DList<T>::DList()':
../../include/dlist.h:41: error: '_head' was not declared in this scope
../../include/dlist.h:41: error: '_tail' was not declared in this scope
../../include/dlist.h: In destructor 'DList<T>::~DList()':
../../include/dlist.h:44: error: there are no arguments to 'clear' that
depend on a template parameter, so a declaration of 'clear' must be available
../../include/dlist.h:44: error: (if you use '-fpermissive', G++ will accept
your code, but allowing the use of an undeclared name is deprecated)
.......
我之前有類似的情況是在static funx未在.cpp檔，instatiate的時候.....
但這次我真的搞不清楚了@@"
_head、_tail明明是Dlist class的private data member，為什麼它會看不到？同時，
adtTest.h也有出現以下complain：
adtTest.cpp:49: error: cannot define member function
'DList<T>::AdtResetCmd::exec' within 'DList<T>'
adtTest.cpp:63: error: cannot define member function
'DList<T>::AdtResetCmd::usage' within 'DList<T>'
......
(adtTest.cpp我都沒碰啊~~~)
我已經確定應該沒少{} (少了，它應該會紅紅的).....
請問像這樣的情形可能有的其他原因是什麼？ (要我砍掉重練？？!)
謝謝大家的回答~

我即使想憑著"浩然正氣"寫程式也不能....因為.....
我只有"一股傻氣".......囧
